SHUTTER-WORKER.-

SPECIFICATION forming part of Letters Patent No. 439,912, dated November4, 1890.

Application tiled May 29,1890. Serial No. 353,662. (No model.)

To a/ZZ whom it may concern.-

' Be it known that I, ALEXANDER F. WARD, a citizen of the United States,residing at Detroit, in the county of Wayne, and State of Michigan, haveinvented certain new and 4useful Improvements in Blind-Operators, of

which the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to new and useful improvements inblind-operators; and the invention consists in providing an ordinarywindow-blind with a plate carrying a gear adapted to mesh with anothergear secured to the Window-casing, and suitable mechanism for operatingsaid gears from the inside of the casing to either open or close theblind and lock it in any adjusted position without the necessity ofopening the window.

The invention further consists in providing means for opening or closingthe slats by the same mechanism used to operate the blind, and, stillfurther, in the peculiar construction, arrangement, and combination ofparts, all as more fully hereinafter described, and shown in thedrawings, in which Figure l is a diagram front elevation of a windowframe and blinds to which my improvement is attached, showing the blindsin several dilferent positions. Fig. 2 is a side elevation of a portionof a window casing, blind, and my improved operator. Fig. 3 is anenlarged front elevation, partly in seotion, showing the slat-operatingmechanism. Fig. 4 is a plan with the blind shown in dotted lines. Fig. 5is an enlarged vertical section on line a: a, Fig. 4. Figs. 6 and 7 aredetail perspective views, more specifically referred to by letters ofreference.

A is a window-casing; B, are blinds; C, the ordinary hinge, and I) myimproved blindoperator, which is preferably formed integral with one ofthe hinges and consists of the following parts: E and E' are plates, theformer being attached to the casing and provided with an arm a,terminating in a socket a', and the latter secured to'blind carrying thepin-gear F and pivot b, which engages in the socket a.

G is the shaft extending through the casing A, the inner end of which isprovided with a knob G. On the outer end of this shaft are sleeved thegear-wheels H and I, the former being nearest the casing and provided onits inner side with a hub c, engaging in a suitable aperture or cut-awayportion c in the plate E and on its outside with the recess'd, while thelatter meshes with the pin-gear F.

e is a pin secured to the shaft G, which is normally in the recess cl,butis adapted to be engaged in suitable notches e and e" inthegear-Wheels H and I, respectively, by a suitable movement of theshaft, thus forming a clutch mechanism, by means of which either gearmay be rotated with the shaft.

J is a spring bearing against the outside of the gear I and adapted tohold it normally in contact with the gear H. K is the lug, preferablysecured to the arm a, engaging with the teeth of the gear I in itsnormal position and acting as a stop to preventit from being rotated.

L is a rock-arm centrally pivoted at f to the plate E', one end of whichis connected by the link M and bracket N to one of the slats of theblind, and the other end terminating in a segmental gear O, adapted tomesh with the gear-wheel I-I.

The bearing k for the pivot is preferably slotted and contains a springg, which normally holds the gear in mesh, but will allow them to bethrown out under sufficient strain.

In practice the operation of the device is as follows: The normalposition of the parts in either the open or closed position of a blindis as shown in Fig. 5., the gear I being held in close contact with thegear I-l by the tension of the spring J, in which position it is lockedfrom turning by the lug K. If the operator wishes to change the positionof the blind, he rst presses on the knob G', which, through the mediumof the shaft G and pin e, forces the gear I out of engagement with thestop K, and by then turning the knob in one way or the other the pin cis engaged in one of the notches e and the gear I rotated, which in turnmoves the pin-gear F, thereby opening or closing the blind. As soon asthe knob G is released, the tension of the spring .I will force the gearI into engagement with the IOO stop K and lock it from further movement;When the blind is in its closed position, the gear H is in mesh with thesegmental gear O, as shown in Fig. 3. If the operator then wishes toopen or close the slats, he first draws in the knob G bringing the pin einto contact with the gear H, when by turning thei former the pin e willbe engaged into the notches e of the gear H, and in its further movementthe Slat will be moved through the medium of .the rock-arm L, link M,and bracket N.

Although I have shown my device as applied to a hinge, it is vevidentthat it could be entirely independent thereof; but in practice I iind itadvantageous to combine the two. It is also evident that any clutchmechanism may be employed which would enable me to operate either of thegears independent of the other in place lof the one shown and described.

What I claim as my invention is- 1. Ina blind-operator, thecombination,with a rotary sliding shaft, of twoindependentlymovablegear-wheels loosely mounted thereon, a crown-wheelrigidly secured to the blind with which the outer gear meshes, a springfor normally holding the same outof engagement,

said gearwheels on the shaft, and means `on the blind for engaging theinner gear to .op-

erate the slats, substantially as described r2. In ablind-operator, thecombinaton,with a rotary sliding shaft, of t-wo independentlymovablegear-Wheels having notches in their inner faces, pins -on said shaft forengaging in said notches, a yspring for normally holding the outer gearin contact with the inner one,

the gear upon the blind, of an intermeshing movable gear-wheel slidinglysecured upon the drive-shaft held in a normally-locked position byengaging with a stationary abut-- ment, and mechanism for releasing saidgear and rotating the blind, substantially as described.

4. In a blind-operator, the combinatiomwith the inverted crown-wheel F,rigidly secured to the blind, of the wheel I, slidingly secured on ashaft adapted to mesh with the wheel F, the stop K, adapted t0 engagewith wheel I and retain the same in astationary position, spring J, fornormally holding said wheel in contact with the lug, andaclutchmechanisrn between the said shaft and gear-wheel, substantiallyas described.

5. The combination of the shaft G, extending lthrough the casing, thegear-wheel H, loosely secured thereon, a lever upon the blind connectedat one end to the shutters and carrying a rack at the otherend adaptedto ymesh with the gear-Wheel H, said rack having a slot in which .thepin f is permitted to -slide,.and a spring-in said slot bearing againstj said pin to normally hol-d the rack in its eX- tended position,.substantially as described.

6. The .combination of the `shaft G, extending through thewindow-casing, the gear-wheel H, a clutch for connecting the two, alever piv- `oted upon the blind, having a slot therein, and

a spring in saidslot for normally holding said v s llever in mesh withsaid wheel H, connected pins on the shaft for engaging and locking:atone end to theshuttersand carrying a rack at the other end adapted tomesh with the gear-wheel H, `substantially as described.

7. The combination ot' the shaft G, gearwheels H and I, vthe pin e uponthe shaft, recesses in the gear-wheels with which said pin is adapted toengage, the gear F, vmeshing with the wheel I, spring J, stop K, slottedley ver having spring-bearing for its fulcrum, the `rack at one end ofsaid lever meshing with `the wheel H,.and a connection between the`blind and the other end of said lever, substantially as described.l

In testimony whereof Iafix my signature .in presence of two witnesses.
